Barium_induced appendicitis was reported in the literature, but its association with lymphoid hyperplasia has not been reported. A 58_year_old woman was admitted to the hospital with right lower quadrant pain. Barium enema examination performed for evaluation of abdominal pain revealed no pathological finding(s). She was readmitted with symptoms of appendicitis 15 days after barium enema. There was an opacity overlying the right sacral ala on her plain abdominal radiograph. She was operated with presumptive diagnosis of barium_induced appendicitis and pathological examination was consistent with lymphoid hyperplasia. Lymphoid hyperplasia and barium_induced appendicitis were discussed in this report.

The ileocecal fold of Treves is a peritoneal structure extending from the antimesenteric surface of the terminal ileum to the base of the appendix. No known pathologic conditions have been previously associated with it. We report a 30-year-old woman with acute onset of right lower quadrant pain. Her history was atypical for appendicitis. Endovaginal ultrasonography did not reveal gynecologic pathology. After a period of observation, the patient underwent diagnostic laparoscopy. This revealed inflammation and necrosis of the ileocecal fold of Treves and a normal-appearing appendix. The lesion was removed and appendectomy was performed. The patient's symptoms resolved immediately after surgery. Histopathologic examination of the lesion revealed fat necrosis, hemorrhagic necrosis, and lymphocytic infiltration. The appendix was normal. In conclusion, infarction of the ileocecal fold of Treves may be included in the differential diagnosis of right lower quadrant abdominal pain. Laparoscopy facilitates the diagnosis and treatment of unusual abdominal lesions.

Acute abdomen is a common presentation to the emergency department (ED), accounting for 5% to 10% of ED visits. Of these, 10% require surgery, and 25% go undiagnosed. Usually, most of the cases of undiagnosed abdominal pain are in young women with pelvic etiologies, although occasionally, unusual causes of abdominal pain lead to diagnostic dilemmas and can have adverse clinical outcomes. We present an unusual etiology of abdominal pain in a young man, who presented with acute onset of right lower quadrant pain accompanied by nausea and vomiting. He was an amateur boxer who had recently intensified his training regimen and admitted to binge drinking for several days before presentation. The initial diagnosis was acute appendicitis, but a computed tomographic scan done revealed a normal appendix. Creatine kinase level was then checked and found to be significantly elevated, and a diagnosis of isolated abdominal wall rhabdomyolysis was made.

Acute abdominal pain can represent a spectrum of conditions from benign and self-limited disease to surgical emergencies. Evaluating abdominal pain requires an approach that relies on the likelihood of disease, patient history, physical examination, laboratory tests, and imaging studies. The location of pain is a useful starting point and will guide further evaluation. For example, right lower quadrant pain strongly suggests appendicitis. Certain elements of the history and physical examination are helpful (e.g., constipation and abdominal distension strongly suggest bowel obstruction), whereas others are of little value (e.g., anorexia has little predictive value for appendicitis). The American College of Radiology has recommended different imaging studies for assessing abdominal pain based on pain location. Ultrasonography is recommended to assess right upper quadrant pain, and computed tomography is recommended for right and left lower quadrant pain. It is also important to consider special populations such as women, who are at risk of genitourinary disease, which may cause abdominal pain; and the elderly, who may present with atypical symptoms of a disease.

Isolated ischaemic caecal necrosis is an unusual event. Because right colon location is less frequent than left one, it may not be considered in the differential diagnosis of right lower quadrant pain. With the typical symptoms (right-sided abdominal pain and tenderness), patients are suspected of having either appendicitis or caecal carcinoma. CT-scan images of caecal wall thickening are often misinterpretated as acecal neoplasm or abscess. We present a case of isolated ischaemic caecal necrosis misinterpretated as a caecal neoplasm.

Although the finding of appendiceal duplication is uncommon, its misdiagnosis and mismanagement may yield poor clinical outcomes and serious medicolegal consequences. Laparoscopic surgical exploration was performed on a 17-year-old male patient with right lower quadrant pain and a history of a previous appendectomy. Inspection of the cecum revealed a second appendix, which was retrocecal, ruptured, and gangrenous. Appendiceal duplication should be considered in all cases of lower abdominal pain, and careful inspection of the cecum for appendiceal anomalies should be performed. The Cave-Wallbridge classification system will be presented to assist surgeons in diagnosing appendiceal duplications.

Abdominal pain is a frequent presenting symptom among HIV-positive patients seeking care at emergency departments. We report a case of a 45-year-old HIV-infected Hispanic man who presented with right lower quadrant pain accompanied by fever, decreased appetite, nausea, and vomiting. The results of a CT scan of his abdomen were normal with no evidence of appendicitis. A colonoscopy was performed and revealed an impacted pill in the appendiceal orifice. The pill was removed endoscopically, and pill impaction has not recurred.

The diagnosis of acute appendicitis has been based on the presence of right lower quadrant pain and guarding. Occasionally, the pain disappears, even in the presence of a continuing appendicular process. This phenomenon is called "the fools' paradise". We report two male patients aged 19 and 17 years with an acute appendicitis confirmed by an abdominal ultrasound in one and an abdominal CAT scan in the other, in whom the abdominal pain disappeared during the evolution. Despite of the absence of pain, both were operated, based on imaging and laboratory studies, confirming the presence of an inflamed appendix.

Cysts of the omentum are rare and most frequently discovered in children. These cysts may cause abdominal distension, pain, or vomiting. Omental cysts with right lower quadrant pain are found even more rarely in adults. We describe a 44-year-old male who had a 2-day history of abdominal pain localized in the right lower quadrant. Before surgery, acute appendicitis with intra-abdominal abscess was suspected, but during the operation, an infected cyst of the omentum, adjacent and adherent to the redundant transverse colon, was found to have been causing these symptoms. Despite the fact that cysts of the omentum have been reported rarely, the operator should be aware that the cyst is a benign entity and the surgical strategy should be different from that for malignancy. We should keep the possibility of omental cyst in mind to avoid unnecessary bowel resection and potentially harmful inappropriate treatment.

A mobile caecum and ascending colon is a rare congenital abnormality. Its presentation as a cause of right lower abdominal pain in an adult is usually mis-diagnosed as acute appendicitis. A 42-year-old civil servant presented with a 2-year history of recurrent right lower quadrant pain of the abdomen. The pain was sharp in nature and persistent in the last 2 weeks and centered mainly in the right side of the abdomen. No other associated symptoms were noted. Laboratory investigations did not reveal obvious abnormality. A diagnosis of acute on chronic lower quadrant pain of unknown etiology was made. The patient was resuscitated and had exploratory laparatomy. No abnormalities were found other than the caecum and the whole ascending colon, which were unattached to the posterior peritoneum. Appendectomy and caecopexy, using a lateral peritoneal flap were performed. The diagnosis of mobile caecal syndrome should be considered in patients with chronic right lower quadrant pain, and appendectomy and caecopexy offers a great relief.
